.TH PMVIEW 5 "" "Performance Co-Pilot"
.SH NAME
\f3pmview\f1 \- configuration file format for performance
.SH DESCRIPTION
This man page describes version 2.1 of the
.B pmview
configuration file format.
.PP
The configuration format supports metrics from multiple hosts or archives.  A
configuration file can specify metrics without a source, with different hosts
and different archives.  However, a configuration file that contains archives
may only have one archive for any one host.  When in ``replay'' mode, any
metrics with host specific sources require an archive to be specified for that
host on the command line or as a source to a previous metric.  The archive must
be the same archive (based on a string comparison of the archive names) of any
archives specified in the configuration file for the same host.
.PP
The time controls will list all hosts that are specified on the command line
and the configuration file in the timezone listing (see
.BR pmtime (1)).
.PP
The configuration file format is based on a two-dimensional grid which
can contain a variety of bars, stacks, links, pipes, labels and other
grids.  The grids resize each column and row to match the size of the
largest item in that column or row.  A configuration file that
contains only one object does not require a grid. The
.B pmview
configuration file starts with an identification header in the first
non-comment line:
.PP
.in 1.0i
.ft CW
.nf
pmview Version 2.1 \f2[command_line]\f1
.fi
.ft R
.in
.PP
The optional
.I command_line
should be the command line with which the tool was launched, if the
configuration file has been generated by another tool.  This is useful for
applications that are to be restarted automatically on the next login, after
the user has logged out while
.B pmview
was still running.
Care should be taken to ensure that the command specified is either a
full pathname or will be found on the PATH available at login.
.PP
All lines which begin with ``#'' are treated as comments and
ignored.  Otherwise, all spaces, tabs and newlines are treated as white space
so multiple commands may be on the same line.
.PP
The syntax for specifying values in the configuration file is consistent for
all commands, namely:
.TP 4n
.I color
A color must be either a
.BR X (1)
color name, a
.BR X (1)
numerical color, or three normalized
.I real
values representing the saturation of red, green and blue.  For example,
the following colors are identical:
.PP
.in 1.5i
.ft CW
.nf
red
rgbi:1.0/0.0/0.0
1.0 0.0 0.0
.fi
.ft R
.in
.TP 4n
.I int
An integer.
.TP 4n
.I metric
A metric consists of an optional source (host or archive), the metric name,
an optional instance list immediately after name, followed by the maximum (or
normalization value).  A colon (``:'') is used to separate a host name from the
metric, and a forward slash (``/'') to separate an archive name from the
metric.  Instances are enclosed in square brackets and comma separated.  Each
instance may be enclosed in quotes.
.IP
For example, some legal metrics are:

.in 1.5i
.ft CW
.nf
kernel.all.cpu.idle 4000
myhost:kernel.all.cpu.idle[cpu0,"cpu3"] 1000.0
/path/to/myarchive/kernel.all.cpu.idle[cpu1] 1000
.fi
.ft R
.in

To assist the process of matching instance names, two further comparisons are
made beyond a simple string comparison.  If the instance name contains
spaces, only the first word in the instance name is required to match the
instance, assuming that the first word is unique.  If the first word is not
unique, only the first matching instance will be selected.  The second
comparison occurs if the first word is a number with leading zeros.  Any
leading zeros will be skipped before comparing the first word again.  This
permits process ids used in the
.I proc
metrics to be easily matched, without specifying the entire instance name.  For
example, to visualize the user and system time of
.I init
use the metric specification

.in 1.5i
.ft CW
.nf
proc.psusage.utime[1]	1000
proc.psusage.stime[1]	1000
.fi
.ft R
.in
.TP 4n
.I name
A name for an object which may be referred to later in the configuration file.
Names must be a single word consisting of all alphanumeric characters, as well
as underscores, dashes and colons.  It is recommended that names do not begin
with an underscore as this may be interpreted as a keyword.
.TP 4n
.I pos
This is the position of the object within the grid.  The syntax of a position
is:
.IP
.in 1.0i
[ [\f2x\f1 \f2z\f1] [ [\f2width\f1 \f2depth\f1] [\f2alignment\f1] ] ]
.in
.TP 14
.I "       x"
The horizontal coordinate (left to right) of the object, starting at 0.  The
default
.I x
is 0.
.TP
.I "       z"
The vertical coordinate (top to bottom) of the object, starting at 0.  The
default
.I z
is 0.
.TP
.I "       width"
The number of columns occupied by the object.  The default
.I width
is 1.
.TP
.I "       depth"
The number of rows occupied by the object.  The default
.I depth
is 1.
.TP
.I "       alignment"
The edge or corner that the object is aligned with.  Possible alignments
include: \f2north\f1, \f2south\f1, \f2east\f1, \f2west\f1, \f2northeast\f1,
\f2northwest\f1, \f2southeast\f1, \f2southwest\f1 and \f2center\f1.
Abbreviations like \f2se\f1 and \f2SE\f1 are also accepted.  The default
alignment is \f2center\f1.
.IP
The size of an object may not be known as the number of instances for some
metrics will vary between hosts and
PMDA
configurations.  Therefore, the position of the object can be used to specify
the likely size of the object, so that the position of the surrounding objects
is appropriately adjusted.
.IP
The following are legal positions:
.TP 21
.ft CW
              0 5
.ft R
The object is centered at grid position 0,5 occupying 1 grid square.
.TP
.ft CW
              1 2 north
.ft R
The object is aligned with the north edge of position 1,2 occupying 1 grid
square.
.TP
.ft CW
              2 2 2 1 east
.ft R
The object is aligned to the eastern edge of position 3,2 and occupies 2 grid
squares (2,2 and 3,2).
.TP 4n
.I string
A string is a series of characters enclosed in double quotes.  A string may
not contain newlines or escaped double quotes.

.PP
There are several parameters that may affect the size, shape and color of
objects when they are displayed.  These parameters are scoped so that they only
alter objects defined later in the same scope.  Therefore, parameter settings
at the top of a configuration file affect the entire scene, unless they are
changed later in the file.  Most of these parameters are also resources.
.TP 4n
\f3_barLength\f1 \f2int\f1
The side length of the
.B _bar
and
.B _stack
blocks.  Default is 28.
.TP 4n
\f3_barHeight\f1 \f2int\f1
The maximum height of a
.B _bar
and
.B _stack
blocks.  Default is 80.
.TP 4n
\f3_baseColor\f1 \f2color\f1
The color of
.BR _bar ,
.B _grid
and
.B _stack
base planes.  Default is rgbi:0.15/0.15/0.15.
.TP 4n
\f3_baseHeight\f1 \f2int\f1
The height of
.BR _bar ,
.B _grid
and
.B _stack
base planes.  Default is 2.
.TP 4n
\f3_gapWidth\f1 \f2int\f1
The gap between blocks in a
.B _bar
object in the X-axis.  The default is 8.
.TP 4n
\f3_gapDepth\f1 \f2int\f1
The gap between blocks in a
.B _bar
object in the Z-axis.  The default is 8.
.TP 4n
\f3_gapLabel\f1 \f2int\f1
The gap between the base of a
.B _bar
object, and any metric or instance labels.  The default is 6.
.TP 4n
\f3_gridWidth\f1 \f2int\f1
The minimum width of a
.B _grid
column.  The default is 20.
.TP 4n
\f3_gridDepth\f1 \f2int\f1
The minimum depth of a
.B _grid
row.  The default is 20.
.TP 4n
\f3_labelMargin\f1 \f2int\f1
The margin around a
.B _label
object.  The default is 5.
.TP 4n
\f3_labelColor\f1 \f2color\f1
The color of
.B _label
and
.B _bar
labels.  The default is white.
.TP 4n
\f3_marginWidth\f1 \f2int\f1
The extra width of a
.BR _bar ,
.B _grid
and
.B _stack
base plane beyond the objects on the plane.  The default is 8.
.TP 4n
\f3_marginDepth\f1 \f2int\f1
The extra depth of a
.BR _bar ,
.B _grid
and
.B _stack
base plane beyond the objects on the plane.  The default is 8.
.TP 4n
\f3_pipeLength\f1 \f2int\f1
Total length of a
.BR _pipe.
The default is the value of
.BR _barHeight.
.TP 4n
\f3_scale\f1 \f2real\f1
The scale applied to the entire scene.  This parameter may not be used within
any objects, only at the top of the configuration file.  The default is 1.0.
.PP
To simplify the specification of colors, a
.B _colorList
and a
.B _colorScale
may be used to define colors for an object which has metrics
associated with it, i.e.
.BR _bar ,
.B _stack
or
.BR _pipe .
A color list may be defined within an object, or named and defined at
the top of a configuration file.  A named color list may then be referenced
within multiple objects:
.TP 4n
\f3_colorList\f1 \f2name\f1 \f3(\f1 \f2color\f1 [\f2color\f1...] \f3)\f1
Associate the
.IR color s
with the color list
.IR name .
The assignment of colors to blocks depends on the type of an
object.  For example, the color list called
.I foo
has the same color three times:

.RS 4
.ft CW
.nf
_colorList foo ( red rgbi:1.0/0.0/0.0 1.0 0.0 0.0 )
.fi
.ft R
.RE

.TP 4n
\f3_colorScale\f1 \f2name\f1 \f2color\f1 \f3(\f1 \f2color\f1 \f2real\f1 [\f2color\f1 \f2real\f1...] \f3)\f1
Associate the
.IR color s
and
.IR real s
with the color list
.IR name .
The initial
.I color
is the default color of the object.  The object will change color to the other
colors when the normalized value of the object is equal to or greater than
each
.IR real .
Therefore, each
.I real
must be larger than the previous
.IR real ,
and should be in the range 0.0 to 1.0.  This scale gradually changes from blue
to red:
.PP
.RS 4
.ft CW
.nf
_colorScale coldToHot blue ( rgbi:0.5/0.0/1.0 0.3
                             purple 0.6
                             rgbi:1.0/0.0/0.5 0.8
                             red 0.95)

There are several different object types which could be found in a
.B pmview
scene:
.BR _bar ,
.BR _stack ,
.BR _pipe ,
.BR _grid ,
.BR _link ,
and
.BR _label .
There is also
.B _xing
which is a special type of the
.BR _link .
The
.BR _bar ,
.B _stack
and
.B _pipe
objects are modulated by metric values, a
.B _label
is fixed text,
.B _link
and
.B _xing
are interconnects and a
.B _grid
is a container of objects, including other
.B _grid
objects, which controls the layout of the scene.
A
.B _grid
object is only required if there are two or more objects in the scene.
.PP
.BR _bar ,
.B _grid
and
.B _stack
objects may have base planes which provide a point of reference for the blocks
as they change height.  A label can be applied to the base plane
.B _grid
object if it is
.B _shown
with:

.in 1.5i
.ft CW
.nf
\f3_baseLabel\f1 \f2name\f1|\f2string\f1
.fi
.ft R
.in

.B _baseLabel
should be used within the scope of the relevant
.BR _bar ,
.B _grid
or
.B _stack
object.  The first ``\\n'' characters in the string will be replaced by a new
line.  Subsequent ``\\n'' characters will be ignored.
.PP
For a scene to be valid it must contain at least one modulated object.
.PP
The objects are defined as:
.TP 4n
\f3_bar\f1 [\f2options\f1] \f3(\f1 [\f2metric-list\f1] [\f2color-list\f1] [\f2label-list\f1] \f3)\f1
A
.B _bar
object represents a collection of blocks.  The number of blocks depends on the
number of metrics and metric instances assigned to the object.  By default, the
blocks are modulated by changing the height of each block.  Alternatively,
blocks may be modulated by changing color, or both height and color.  Each
color in the
.I color-list
is assigned to each metric.  Therefore, multiple instances of the one metric
will have the same color.  The
.I options
that may be passed to a
.B _bar
object are:
.RS 4n
.TP 4n
.I pos
The position of the
.B _bar
object within the current
.B _grid
object.
.TP 4n
\f3_col\f1|\f3_row\f1
Position the blocks so that each instance is in a column
.RB ( _col )
or a row
.RB ( _row ).
This implies that each different metric is in a separate row or column,
respectively.  The default is
.BR _col .
.TP 4n
\f3_show\f1|\f3_hide\f1
Is the base plane visible? Default is
.BR _show .
.TP 4n
\f3_ymod\f1|\f3_colormod\f1|\f3_colorymod\f1
Modulate the blocks by adjusting their height
.RB ( _ymod ),
color
.RB ( _colormod )
or both height and color
.RB ( _colorymod ).
.TP 4n
\f3_cube\f1|\f3_cylinder\f1
Set the shape of the blocks.  The default is
.BR _cube .
.RE
.RS 4n
.TP 4n
\f3_groupbymetric\f1|\f3_groupbyinst\f1|\f3_groupbyrow|\f1|\f3groupbycol\f1
Set the grouping of blocks when launching other tools. For tools like
.BR pmchart (1)
some views may generate many small charts which cannot be drawn entirely within
the screen.  Another problem is it may be more appropriate to generate charts
with the same instance in each chart, rather then the same metric.  The group
specifiers control the algorithm used so that a separate chart will be drawn
for each
.B _metrics
specification
.RB ( _groupbymetric ),
for the first, second etc. instance of each
.B _metric
.RB ( _groupbyinst ),
or by the rows and columns of the
.B _bar
object depending on
.B _row
or
.BR _col .
The default is
.BR _groupbymetric .
.PP
The options must be specified in this order, although preceding options are
not required.  Therefore, this is legal:

.B _bar
object depends on the
.B _row
or
.B _col
orientation of metrics and instances, and whether the label is read
.B _towards
the

A
.B _grid
object is a container for objects, including other
.B _grid
objects.
The rows and columns of a
.B _grid
object are resized to the largest object in the row or column.  If an object
spans multiple rows and/or columns, those rows and columns may be partly
resized to contain the object.  However, the resizing of rows and columns for
objects occupying multiple rows and columns occurs after resizing for objects
occupying only one grid square.

A collision between objects occupying the same squares will be reported as an
error message and the later object will be ignored.

The options to a
.B _grid
object control the position
.RI ( pos )
of the
.B _grid
object in the parent
.BR _grid ,
and indicate whether to
.B _show
or
.B _hide
the
.B _grid
base plane.  By default, the base plane is hidden.

The parameters described above may be specified within the brackets of a
.B _grid
object, however they only apply to the objects within the
.BR _grid ,
not the
.B _grid
itself.  For a parameter to be applied to a
.B _grid

A
.B _xing
is a special kind of link which is used to draw a pair of links which
cross each other. To convey the visual impression that the links do
not join, one of the links is drawn as a ``broken'' cylinder.
.I col
and
.I row
define the position on the enclosing grid.
.I columns
and
.I rows
define the size of the bounding box. The end points of the crossing
cylinders are placed exactly in the center of the corner cells of the
bounding box and four small cylinders or stubs are used to join the
perimeter of the bounding box with the end points on the crossing
cylinders. Four
.I dir
values define the orientation of the stubs, starting at the upper left
corner of the
.B _xing
and proceeding clockwise, such that respective stubs are used to join
the point of the compass with the center on the cell (see example).
